What is Hepatitis?
- Hepatitis is an inflammation of the liver.
- The condition can be self-limiting or can progress to
fibrosis(scarring), cirrhosis or liver cancer.
- Hepatitis viruses are the most common cause of hepatitis in the world but other infections, toxic substances (e.g. alcohol, certain drugs), and autoimmune diseases can also cause hepatitis.
Note: Autoimmune hepatitis is a disease that occurs when your body makes antibodies against your liver tissue.
Types of Viral Hepatitis
- Viral infections of the liver that are classified as hepatitis include hepatitis A, B, C, D, and E.
- A different virus is responsible for each type of virally transmitted hepatitis.
- These 5 types are of greatest concern because of the burden of illness and death they cause and the potential for outbreaks and epidemic spread.
- In particular, types B and C are the most common cause of liver cirrhosis and cancer.
